MADRID – A man in the state of Galicia was arrested by Spanish National Police on Tuesday evening for "inciting jihadist terrorism" and "humiliating the victims of terrorism," the country's Interior Ministry announced.

A ministry statement Wednesday said the Spanish national also had an online outlet through which he sold the clothes, which include baby onesies with jihadi emblems, and T-shirts with images of Islamic State group attacks.

He also sold T-shirts and sweatshirts bearing an image of British hostage Alan Henning kneeling beside his suspected jihadi executioner that sold for $15.50 and $18, respectively.

Police searched the man's home and workplace, confiscating a number of documents and items.

The ministry said the man is an active social media user who often expressed radical views in line with those of terrorist organizations, as well as promoting ISIS and other groups, belittling jihad victims and advocating violence.

Spain has arrested some 50 suspected jihadi militants and recruiters this year.
